Fabula Rasa

Fabula Rasa is an interactive, improv-driven VR narrative adventure developed and published by Brazilian studio ARVORE (creators of Pixel Ripped and The Line). Scheduled to launch on December 3, 2026 on the Meta Horizon Store for Meta Quest 3 and Meta Quest 3S, the game places you inside a suspended cage in the middle of a picturesque medieval town square, moments away from being dropped into a monster pit. With no pre-written dialogue trees, your only way out is to speak aloud into your headset microphone and persuade nine AI-powered townsfolk to plead your case before the King arrives.

Real-time voice improvisation and AI-driven townsfolk

Rather than clicking through static dialogue branches, every playthrough of Fabula Rasa begins with a blank slate: a royal scribe asks for your name, your trade, and the crime you stand accused of, and you invent your own backstory on the spot. Designed in collaboration with professional improv comedians, the game treats your spoken words, props, and character customization as prompts that shape an unpredictable comedic stage play.

• LLM-powered personalities and AI director: Each of the nine townsfolk is driven by large language models (combining Anthropic's Claude for character personality and dialogue, an AI director powered by ChatGPT to track town state and plot progression, ElevenLabs voice synthesis, and Convai for engine integration), allowing characters to listen, remember your claims, pick up objects, and pursue their own agendas based on their emotional state.
• A colorful medieval cast: Converse with nine distinct characters circling your cage—including King Otis II (a vain, tantrum-throwing tyrant), Everard (a lovestruck executioner), Wyselda (a scheming potion-shop witch), Belladova (a flamboyant bard), Sir Person (three neurotic cats in a suit of armor), Billy (a lonely goblin), Wilkin (a sadistic spectator), Pete (a monster in existential crisis), and Oswald (a bureaucracy-obsessed ogre).
• Handcrafted theatrical world: All visual art and environments are handcrafted without generative AI art, styled like a vibrant medieval stage production where being charming, empathetic, ridiculous, or a total menace are all valid survival strategies.
